MPROVEMENT IN PASSENGER STEP-REGISTERS.

Specification forming part of Letters Patent No. 210,264, dated November2G, 1878; application filed December 10, 1877.

' iication.

This invention relates to a perfectly reliable and inexpensive apparatusfor automatically registering the number of passengers entering astieet-car or other vehicle.

The nature of our invention is clearly indicated in the accompanyingdrawing, whereon Figure l represents a side elevation, part ot' which isshown in section, and Fig. 2 a horizontal cross-section of the same.

A represents the tloor of a car, tothe rear of which is secured a metalframe, B, provided with lugs b Z) for kholding in a horizontal positiona rod, c, on which is pivoted a step, D, that is furnished on its underside with an angularly-shaped lng, c, for operatin g on afriction-roller7 f, the latter fitted in the rear of a sliding rod, g,which is provided with a pin, h, and spring i', whereby it is kept, whennot in operation, in a backward position.

Connected with the forward end of the aforesaid rod y is the lower endof a lever, It', the center of which is pivoted to the lugs t" t', sothat its upper end, Il, may operate a horizontal lever, l, that ispivoted to the under side of the tloor, as at a, in order that anymovementthereof may be communicated through a link, m, to the lower endofa forked lever, n, which is suspended on the indicator-shaft o, thejournals of which operate in the upright bearings p p', the latterprovided with a marked dial, l,

around which the index-finger 2 is operated bya wheel, q, that is keyedor otherwise secured to the shaft o, so that its teeth may be engaged bya spring-pawl, r, and check s, as shown.

To the horizontal levert is connected, by means of a wire or cord, t, ahammer, a, for striking a gong, c, the instant each registration takesplace.

The operation of our invention is as follows:

The moment a persons weight is thrown on the step the rod gis, by thewedge c, driven forward to such an extent as to change the position ofthe levers It and Z, the movement being communicated by the link m tothe lcver a, the pawl of which causes the toothed wheel to move forwarduntil the check s springs over one tooth, in which position `the wheelis securely held until the apparatus is again operated. The instant thestep is released of the weight of the passenger by his entering the carthe mechanism iiies back to its normal position, thus causing t-he pawlr to engage a second tooth, and hence be ready for another operation.

This apparatus, it will be perceived, is operated by the passenger, bothas he enters and leaves the car; and hence, to ascertain the eX- actnumber of passengers carried it is necessary to divide the numberindicated on the dial by two.

The gong, as a matter of course, maybe placed in any desired position bysimply shortening or lengthening the link or wire, as the case may be,which connects with the hannner thereof.

Having described our invention, what we claim as new, and desire tosecure by Letters Patent, is-

In an automatic passenger-register, a pivoted step, D, provided withwedge c, for operating on a friction-roller, j', that is fitted in therear end of a sliding rod, g, as described, and for the purpose setforth.

In testimony whereof we have hereunto signed our names.
